Alu diff pins 2x ##335081 – I opt for the Alu diff pins in order to keep the drivetrain as heat resistant and rigid as possible, and still keep it lightweight. Using the separated cross pins also allows me to quickly change for the 2-gear configuration by just removing one pin with gears.

Graphite diff case 2x #364912-G + Graphite diff cover 2x #364920-G – The graphite diff case and cover help to keep the XB4 differentials more heat resistant, especially since we use quite stiff diff settings. Also, it makes the diff and drivetrain lighter in weight, which is always welcome on high grip.

2mm front and rear anti-roll bars 2x #362489 – The 2mm anti-roll bars help generate more stability and carry more corner speed on high grip conditions, also reducing the possibility of flipping the car with traction roll.

Rear adjustable drive axle 2x #325341 – I use the adjustable axle in order to always keep the desired rear drive shaft length, especially when changing the width of the car on arm holders or rear hub.

Adjustable drive axle shims #325390 – Must be used with the adjustable rear drive axle.

Rear Alu hubs 2x #323356 – Aluminium rear hubs help to get more stability from the rear end of the car, carry more corner speed and also provide more rigidity in hard crashes.

Front Alu steering blocks and hubs - set #360900 – Aluminium front hubs and steering blocks feature the 7° caster option, which helps the XB4 carry more corner speed on high grip. It also enhances the stability of the front end of the car.

Graphite chassis side guards #361277-G – Graphite mixture of side guards provide more stability and help carry more corner speed, reducing the overall grip.

Graphite Rear chassis brace #361297-G – The rear graphite mixture chassis braces provides more stability on the rear end of the car and helps carry more corner speed, reducing the overall rear grip of the car.

Graphite Front chassis brace #361286-G – The front graphite mixture chassis braces provides more stability on the front end of the car and helps carry more corner speed, reducing the overall front grip of the car.

Graphite servo saver #362510-G - Graphite mixture of the servo saver gives the driver more precise steering from the car.

Slipper eliminator set #364102 (+ needed parts: dogbone #365436, bulkhead #364024, topdeck #361176) – The slipper eliminator (solid axle) is a must for carpet Stock racing, as it gives the car the most drive out of the corner with reduced rotating mass compared to the slipper.

HUDY 25T Alu servo horn #293406 – Aluminium servo horn provides more rigidity as well as gives more precise feeling from the steering of the car.

25T motor pinion #305925 – My gear choice for the high speed track in Florida.

HUDY motor fan #293110 – To help keep the motor temperature as low as possible, a motor fan is necessary, my choice was the 30mm HUDY fan with external soldering tabs.

HUDY chassis sticker #209200 – As a mandatory rule at the event to use a chassis protector, I chose the HUDY chassis sticker to protect my car as well as the carpet, giving the chassis a nice look.
